WRITING, DRAWING, on RULING' PEN Application filed March 16,1932, serial No. 599,259, and in Germany March 18} 1931.

'This invention relates to writing, drawing or ruling pens consisting of two connected parts, a nib adapted to be attached to a pen holder and an overlying member which is spaced from the nib-to provide a narrow space between them for the ink. i

The invention has for its object to provide a writing, drawing or ruling pen of this kind which can" be easily cleaned and in which the width of the linedrawn, and the intensity 'of the ink flow is unaffected by the cleaning of the parts. 9

The invention also has for its object to, provide a pen which can be readily and cheaply made by standard methods used in pen manufacture and with the usual mate-rials employed in pen manufacture.

The writing, drawing or ruling pen according to the present invention consists of a spring metal nib and a superposed or overlying spring metal member or tongue which is pivotally attached to theshank of the nib, the axis of rotation being at right angles to the shank of the nib, and which is arranged to normally lie with one extremity adjacent the extremity of the ni In a preferred form of my invention I provide close to the point of the nib spacing means to maintain the tongue in a correct distance from the nib. This manner of separating the parts is of main importance, if

the pen is designed as a ruling pen, as it prevents any variation of the width of the stroke which might be caused by flexing of the nib when the nib is pressed for example too hard against the ruler or straight edge. Thiscorrect maintaining of the distance between the parts enables the parts to be made of thinner and more springy steel than has heretofore been generally possible in the manufacture of pens of such kind. 7

Further particulars of the invention will be apparent from the following description.

In order that the invention maybe more clearly understood, reference is hereinafter made to the accompanying drawing which illustrates in an enlarged scale two'forms of the invention.

Fig. 1 is a front view of a drawing pen according to the invention and Fig. 2 is a longitudinal sectionalview ongthe line IIY-II ofFig.1'.

tially parallel to the shank of. the nib. An overlying member or tongue 6 is. pivotally to the drawing, the pen consists is a front view of a rul'i'ng pen in width the shank of the nib and bent at lls'ubstan attached to the lugby means of a pin or rivet 53011 which the member 6 rotates,'the

axis of rotation being at right angles to the shank of' the nib. The member 6 'isbent inwards so thata part 6a thereof lies close to the'nib portion 1a and substantially paral-' lel with it and its end isbent outwards at 7 parallel-[with the nib end 2. An indentation 8 in the portionytia bears onthe nib portion 1a and separates the two parts. The member 6 is extended beyond the pivot 5 andtheflcnd' of the extension 6?) is bent back towards the the nib shank 1. -An 'indentatio'n' 9 in .the extremity 106 snaps into a hole 10 in the nib nib shank andits extremity 106 bears against shank when the partsare'in position fo'r' use. i The ink flows through a hole ll in'the nib I portion 1a into the'space between the nib port1on 1a and the opposed part 6aof the ton2;ue6..v

The rulingpen shown in Figs. 3 '5 is similar in construction to the drawing Figs. land 2 but the reduced pa'rt12 of the nib and'the opposed part 13 ofthe 'overly ing tongue are straight andcf, equal length and are similarly beveled off at both sides so pen of r .1 I

as. to'provide two triangular points opposite eachother. Except 'at the triangular end, the

tonguelpartl3 is narrower than the nib part 12 to preventthe ink from rfunning on to'the ruler or straight edge; i
